4 Claims.-, (01. 1115331 The present invention relates to new and usefulimprovements in seeding machines and has for its primary object. toprovide,.in a manner as hereinafter set forth, an implement of thischaracter comprising novel means for facilitating-the planting ofhorizontally or laterally undulating rowsfor obstructing the blowing ofwind and snow down said rows, thereby preventing wind erosion of thesoil in addition to protecting the crop against damage.

Other objects of the invention are to provide a seeding machine of theaforementioned character which will be simple in construction, strong,

durable, highly efficient and reliable in operation,.

man-

and advantages of the invention will become apparent from a study of thefollowing specification, taken in connection with the accompanyingdrawings wherein like characters of reference designate correspondingparts throughout the several views, and wherein: I

Figure 1 is a top plan view of a seeding machine embodying the presentinvention. I

Figure 2 is aview in rear elevation of the undulating marker.

Figure 3 is a sectional view,-taken on the line 3-3 of Figure l. i

Figure 4 is a view in vertical section, taken substantially on the line4-4 of'Figure 3.

Figure 5 is a fragmentary view in vertical section, taken substantiallyon the line 55 of Figure 1.

Referring now to the drawings in detail, it will be seen that referencenumeral I designates a main frame. The frame I is mounted on an axle 2having journaled thereon supporting wheels 3. Gangs of disks 4 aremounted beneath the forward portion of the frame I. The frame socketjoint I3. Coil springs I4 are mounted on therods I2 and engaged withthe-stops II for yieldingly urging the'togglesections 8 and 9tosubstantially I 'I is to be connected in any suitable manner to 1 atractor. The usual guides 5 project laterally in opposite directionsfrom the frame I.

Projecting laterally from the side portion 6 of the, frame I is an armwhichis designated generally by reference numeral I. The arm I comprisesinner and outer toggle sections 8 and 9 in the form of frame structureswhich are pivotally connected at III to permit said arm to fold orcollapse in a vertical plane. Abutting stops II rise from the pivotallyconnected ends of the toggles 8 and 9 for positively limiting theopening movement thereof. In the embodiment shown,

ward open or extended position.

. Theinner end ofthe toggle section 8 is pivotally connected at I5 tosuitable brackets IS on the side portion 6 of the frame I. Thus, the armI may be swung upwardly to inoperative position on the frame I when saidarm is not in use.

Mounted on the outer or free end portion of the toggle section 9 is aspindle IT. The spindle II projects from the lower end of a verticalarmI8 which'is pivotally mounted at an intermediate point, as at I9, on thetoggle section 9 for swinging movement in a vertical plane. A mark--ving disk 20 is mounted on the outer end portion of the spindle I]. Alsomounted on the spindle I1 is a gage Wheel 2 I for the disk 20.

A lever 22 is pivotally mounted at an intermediate point on the outertoggle section 9. A rod 23 connects the lever 22, at one end, to theinner toggle section 8. The other. end of the lever 22 is connected by'arod 24 to the upper end portion of the arm I 8. The construction andarrangement is such that the marker 20 is maintained in a verticalposition as the arm I opens and closes.

Mounted on the wheel 3 which is adjacent the arm I is a ring gear 25.Also mounted on this wheel is a cylindrical cam 26 which encircles thegear 25 inspaced concentric relation thereto. A drum 21 is journaled onthe adjacent end portion of the axle 2. A cable 28 has one end securedto the drum 2'! for winding thereon. The cable 28 is trained aroundguide pulleys 29 on the adjacent portion 6 of the frame I and has itsother end connected to a bracket 30 on the outer end portion of the armI for folding or closing the toggle sections 8 and 9 against the tensionof the coil springs I4.

Mounted in the portion 6 of the frame I, adjacent the gear 25 and thecam 26, is a housing 3| through the lower portion of which the axle 2passes. extends rotatably into the. housing 3I around the axle 2. Gears33 and 34 are fixed on the hub 32.

A frame structure 35 is mounted in the housing 3| and journaled thereinare parallel shafts 36 and 31. The shaft 36 projects laterally from thehousing 3I and has fixed thereon a gear 38 which is driven by the gear25. Gears 39 and 40 are journaled on the shaft 31. The gear 40 drivesthe gear 33. The gear 39 drives the gear 34 through a comparatively widegear 4|.

The drum 2! includes a hub 32 which ing 3|. The gear 42 is engageableselectively with the gears 39 and 40 and is also movable to a neutralposition out of engagement with both and has journaled on its outer enda roller 45- which rides on the cam 26. On its other end, the rod 43 isprovided with ahead 46 A, coil spring 41 on the shaft 36 is .engagedwith the gear 42 for yieldingly urging the roller 45 against the cam 26through the fork 44. A hand lever 48 is pivotally mounted on the framestructure 35 and operable in an opening provided therefor in the top ofthe housing 3i. The lever 48 includes a yoke 49 on its lower end whichstraddles the rod 43 and which is engageable with the head 46 forshifting the gear 42 against the tension of the coil spring 41.

- It is thought that the operation of the device will be readilyapparent from a consideration of V the foregoing. Briefly, with the gear42 engaged with the gear 40, as seen in Figure 4 of the drawings, thedrum 2! is connected to the adjacent wheel 3 for rotation thereby in thesame direction. Thus, the cable 28is wound on the drum 2'! and thetoggle sections 8 and 9 of the arm-1 are folded or closed in a verticalplane against the tension of the'coil springs M for drawing the markingdisk 20 inwardly toward the implement. During this operation, the roller45 is riding on the high portion of the cam 26. When'the inward movementof the marking disk 20 has been completed the low portion of the cam 26reaches the roller 45 and permits the spring 41 to shift the gear 42into engagement with the gear 39 for reversing the direction of rotationof the drum 21. In this manner thecable 28 is paid out or unwound fromthe drum21 thereby permitting the springs M to extend or open the arm Iwith the assistance of the weight of the toggle sections 8 and 9 forshiftingthe marking disk 20 outwardly or away from the implement." Theforegoing operation is repeated the length of the field or row and itwill thus beseen that a laterally or horizontally undulating markwill beleft on the field. As hereinbefore stated, the members 22, 23 and 24,swinging the arm I8 on its pivot I9, maintain the marking disk 20in avertical position at all times. The

undulating mark which has been left on the field serves as a guide, inconjunction with one of the "A gear 42 is slidable on the shaft 36 inthe housusual members 5 of. the implement when the first row is planted.The succeeding rows are then planted by following the adjacentpreviously planted row.

It isbelieved that the many advantages of a seeding machine constructedin accordance with the present invention will be readily understood andalthough a preferred embodiment of the implement is as illustrated anddescribed, it is to be understood that changes in the details ofconstructionand in the combination and arrangement of parts may beresorted to which will fall within the scope of the'invention asclaimed.

Havin described the invention, what is claimedas new is:

1. A seeding machine comprising a frame, supporting wheels for saidframe, an arm hingedly mounted on the frame, a marker on the arm, andmeans connecting the arm to one of the wheels for actuation thereby foralternately shifting the marker on the outer end of the arm, and meansoperatively connecting one of the wheels to the arm for opening andclosing the sections thereof for shifting the marker laterally.

' 3. A seeding machine-comprising a frame, an axle mounted on the frame,supporting wheels mounted on said axle, a drum rotatably mounted on theaxle, means operatively connecting the drum to one of the wheelsforalternately rotating said drum in opposite directions, a markermounted laterally of the frame and movable inwardly and outwardlyrelative thereto, and a cable connected to the marker and to the drumfor alternately winding on and unwinding from the latter and therebyreciprocating said marker laterally.

4. A seeding machine comprising a frame, supporting wheels for theframe, a toggle arm mounted laterally on the frame, a marker on saidtoggle arm, and a cable, operable by one of the wheels, connected tothetoggle arm for opening and closing the same for shifting the markerlaterally.
